Beans and TreeMap

[Heiko Ortmann]

Hello,

I want to setup a bean and I am not sure, weather it is possible in the following way:

<util:map map-class="java.util.TreeMap" id="idModel">
<entry>
<key>
<bean class="business.CategoryTO">
<property name="description" value="Userdaten" />
</bean>
</key>
<list>
<bean class="business.FieldTO">
<property name="title" value="Name" />
</bean>
<bean class="business.FieldTO">
<property name="title" value="Rechnungslegung" />
</bean>
<bean class="business.FieldTO">
<property name="title" value="Telefon" />
</bean>
<bean class="business.FieldTO">
<property name="title" value="E-Mail" />
</bean>
<bean class="business.FieldTO">
<property name="title"
value="Erwartetes Lieferdatum" />
</bean>
</list>
</entry>
</util:map>

Is it possible to use not String objects as key and value in a Map Bean?

Thank you and Best Regards
Heiko

Please, use CODE tags when you post code and/or XML here. It makes it so much more readable!

And back to your question, sure it is possible. Your snippet looks ziemlich gut.

Did you encounter some problem with it?

Thank you for the advice, I will use the tags next time.

Indeed the next error message regarding the JSTL view and the foreach command. Now the keys are not a String anymore and

<c:forEach items = "${model.userInformation}" var = "userinfo">

doesn't work.

I solved the problem. I separated the values and created 2 maps with references to the values: code example:

	<util:list id="userdaten">
		<bean class="business.FieldTO">
			<property name="title" value="Name" />
		</bean>
		<bean class="business.FieldTO">
			<property name="title" value="Rechnungslegung" />
		</bean>
		<bean class="business.FieldTO">
			<property name="title" value="Telefon" />
		</bean>
		<bean class="business.FieldTO">
			<property name="title" value="E-Mail" />
		</bean>
		<bean class="business.FieldTO">
			<property name="title"
				value="Erwartetes Lieferdatum" />
		</bean>
	</util:list>

	<util:map map-class="java.util.TreeMap" id="idModel">
		<entry key="userdaten" value-ref="userdaten" />
	</util:map>

	<util:map map-class="java.util.TreeMap" id="idModelEmail">
		<entry>
			<key>
				<bean class="business.CategoryTO">
					<property name="description" value="Userdaten" />
				</bean>
			</key>
			<ref bean="userdaten"/>
		</entry>
</util:map>

I use the maps at the position that I need.

Spring is a very flexible framework

Thx alot and BR
